Application filed December To (ZZZ c. 171 am it may concern it .lrnown that T, Romnrr Den RIDDLE, a citizen of the Uni ed States of America, and a resident oi"; ozurtanbnrg. county 01" tipartanburg, and State of South. Carolina, have invented certain new anduseiliul improvements in Undercasin tor h Iotor-Vehicle Engines. of which ti "following is a :l'ull and clear: specification. I

.The object of this invention is to so construct the under-casing; that it may be removed in sections without removing the motor, to thereby permit ready access to the working parts within the casing, as more fully hereinafter set forth.

In the drawing Fig. 1 is a side elevation showing my invention applied to the well-known Ford engins;

Fig. 2 is a detail perspective view of one of the banners;

Fig. 3 is a plan view of the top part of the engine-casing removed.

In the drawing, the under-casing is constructed ot two sections 5 and 6 divided transverscl y at 7, this divisional point lying just in front of the fly-wheel easing 8 which is a part of the rear section 6, this section 6 also consisting of the part 9 which encloses the transmission and the magneto.

The forward member 5 forms the housing for the cranks and is bolted. as shown, to the upper easing member of the engine. The rear member 6 of the bottom casing is also bolted, a shown, to the upper engine casing. These two sections 5 are bolted together by bolts 10 at their adjoining edges, the sections 5 and 6 being flanged for the reception of the bolts and a suitable gasket being laid between the flanges. I

The rear section 6 is hung to the chassis frame-bars 11 by means of a hang-er, consisting of two parts, an upper part 12 and a lower part 13. These flat vertical parts are removably securedtogethe-r by bolts 14. The upper member overhangs and is bolted down to the frame-bar 11 by a bolt 15, and the lower member 13 is bolted to the casing member 6 in the usual manner. In addition to the main hanger just described, I employ a supplemental hanger consisting" of abar or arm 16, the forward end of which lies under the flange on the top edge of the casing; member 5 and the rear end of which extends upwardly and rearwardly and-lies upon the Specification of Letters Patent.

top face of the hanger member 12, being bolted thereto by the aforesaid bolt 15.

lVith the structure thus described, it will be. observed that either the front member 5 or the rear member 6 of the casing may be removed independently without disturbing the motor, thereby greatly saving .in time and labor in the matter oi cleaning and repairing); the parts enclosed by the undercasing. In removing the front easing, it is simply necessary to unbolt the rear ends of the bracket 16 from the-hangers by removing bolts 15 and to take out the bolts 10 and also the usual bolts fastening this part of the casing to the upper part of the engine casing, whereupon the casing member 5 may be entirely detached without disturbing either the motor or the rear member 6 of the casing. In removing the rear member 6 it is simply necessary to remove the bolts 14: connecting-the hanger members and also, of course, the bolts connecting: said member 6 to the upper part of the engine casing, whereupon this member 6 may be disconnected without disturbing the motor or even the forward member 5 and its hanger.

If the joint between the sections 5 and 6 incline forwardly, as shown, then it will be necessary to loosen the rear cap 17 ot' the usual universal joint slightly rearwardly. It is desirable to thus incline the joint between the members 5 and- 6 in order that the trout section 5 will assist in supporting the rear section 6, thereby to some extent relieving the bolts of strain.

The nature and scope of the invention having been thus indicated and its preferred embodiment having been specifically described, what is claimed as new is:

1. In combination with a supporting frame, an'engine casing consisting of an up per part and a lower part, this lower part beingdivided transversely. means for securing: the adjoining edges of the divided parts together, and a hanger means for the two parts consisting: of independent hangers for said two parts, one of said hangers consisting of two separable parts bolted removably together.

2. In combination with an upper engine casing and a lower or under-casing, this latter being divided transversely and having its parts thus divided bolted removably together, and independent banger means for the two members of said under-casing.

3. An engine casing consisting of an upper member and a lower member bolted together, said lower casing being divided transversely into two independently-removable parts, hanger means for sa1d lower member consisting of a rear hanger for the rear part having its lower end bolted to the rear part and its upper and bolted to the supporting frame, this rear hanger being made of two parts removably bolte together to permit the lower part to be detached from the up er part without disturbing the upper part 0 the hanger, and hangers for the forward part of the under-casing whose upper ends are removably bolted to the upper parts of the rear hangers.

4. In combination with an upper engine casing and a lower or under-casing, this latter being divided transversely and having its parts thus divided bolted removably together, and independent han er means for the two members of said 1111 er-casing, the line of division between said two parts inclining downardly and rearwardly.

5. In combination with a vehicle frame, an engine casing consisting of an upper member and a lower member bolted together, the lower member being divided transversely to form a rear part and a forward part, a pair of divided hangers for one of said parts, the upper ends of these divided hangers being secured by a vertical bolt to the vehicle frame, and a pair of hangers for the other part whose upper ends are secured to the frame by the same bolts that secure the other hangers to the frame.

6. In combination with a vehicle frame, an engine casin whose under member is transversely divided, bolts securing these two parts together at the line of division, a pair of hangers for the rear part, each of these hangers consisting of two parts having vertical portions which overlap and bolts securing these vertical portions separably together, and a pair of hangers for the front part of the under member.

In testimony whereof I hereunto afiix my signature.
